A prison cell is pictured inside Alcatraz 22 December 2006 on San Francisco Bay in California. Sometimes referred to as "The Rock", the small island of Alcatraz served as a lighthouse, then a military fortification, and then a federal prison for the area until 1969, when it became a national recreation area. At present the island is an historic site supervised by the National Park Service as part of the Golden Gate National Recreation Area and is open to tours. Visitors can reach the island by ferry ride from Fisherman's Wharf in San Francisco. It is listed as a National Historic Landmark. The United States Census Bureau defines the island as Block 1067, Block Group 1, Census Tract 179.02 of San Francisco County, California. It is home to the now abandoned prison, the oldest operating lighthouse on the West Coast of the United States, early military fortifications, and natural features such as rock pools, a seabird colony (mostly Western Gulls, cormorants, and egrets), and unique views of the coastline.

HOUSTON (AP) — A now-former parole officer in the Texas prison system has been sentenced to five years in federal prison for accepting bribes from a suspected heroin dealer.

Crystal M. Washington, also known as Crystal Bureau, worked at the Texas Department of Criminal Justice office in Houston before being arrested and fired.

Washington in December was convicted of conspiracy to possess with intent to distribute heroin, plus conspiracy to commit extortion.

Prosecutors say Washington, who was sentenced Friday, accepted bribes from the drug-related parolee from 2009 and 2012. She also warned the parolee about a Houston police investigation.

Investigators say Washington also accepted bribe money from another parolee in May 2012.
